Ceramic Foam Filter For Foundry removes these impurities from molten aluminum during the aluminum casting process. Typically, these filters are made of ceramic materials to withstand the high temperatures associated with molten aluminum.

Molten aluminum usually contains entrained solids, which are harmful to the final cast metal product.
These entrained solids usually come from three sources.
1. Alumina particles, the floating oxide layer on the surface sucks them into the liquid stream.
2. Furnace lining particles entrained by molten aluminum, debris from conveying troughs and other parts of molten aluminum processing equipment.
3. Flowing aluminum stream. Some particles are precipitates of insoluble impurities, such as intermetallic compounds, borides, carbides, or precipitates of other aluminum compounds, such as chloride.
When these impurities appear in the final cast product after the molten aluminum has solidified, they can cause the ductility of the final product to decrease or the finishing characteristics of the final product to be poor.

Ceramic Foam Filter For Foundry completes the filtration process of removing entrained solids from the liquid by passing the solid-laden liquid through a porous filter medium that does not pass through the solid.
In general, filtering molten metals, especially aluminum, poses special problems because liquids are very aggressive and it is difficult to find filter media that can withstand liquids.

Ceramic Foam Filter has excellent resistance to erosion and corrosion of molten aluminum. The filter can effectively remove inclusions, reduce residual gas and provide laminar flow. Therefore, the significantly clean metal after the filtration can improve the quality of castings.
-Reduce waste related to inclusions.
-Reduce costs related to inclusion of defects.
-Improve productivity through higher extrusion or rolling speeds.
